DIY Smart Thermostat 1 Year In

It has been about a year since I installed the homemade thermostat. So far, everything has been working really well. The biggest modification I have made so far is the 3D printed enclosure.

I also added the remote temperature sensor to save energy at night. Additionally, I added some historical data tracking to the openHAB interface and created a weekly email of stats that I get every Saturday.
